Title: Improvements relating to electric switches, particularly tumbler and micro-break type switches
IPC: H01H1/16
Filed: 1948-03-30
Abstract: 637,628. Tumbler switches. FUKE, F. C. March 30, 1948, No. 8935. [Class 38 (v)] Means are provided for positively actuating the contacts of a tumbler switch in the event of an abnormal condition, e.g. jamming or welding together of the contacts. One side of a U-shaped operating handle 10, Figs. 1 and 2, carries a moving roller contact 4 urged into engagement with a fixed contact 3 by a tensionspring 22 acting between a pin 23 on the handle and a pin 24 in a recess 25 in the switch base 1, said spring serving to floatingly support the handle in the base. The other fixed contact 2 is spaced from contact 3 by a small air-gap and has an upward extension 2a engaging projections 19, 20 on the handle which act as limit stops. In moving the handle from the " off " position shown the spring will snap it to the " on " position when the mid-position is reached and cause the roller to bridge contacts 2, 3. In the event of an abnormal condition occurring, the handle can be pivoted about the extension 2a in either of the limiting positions to force the contacts open or closed. In order to balance the handle the other side thereof carries a pin 11 moving in a slot in a bracket 12 or it may carry a moving contact similar to the roller 4. The bracket 12 is extended at 15a to form a pivotal stop similar to 2a. Fig. 4 shows a modification wherein a compression spring guided by a plunger 32 urges the handle 10 outwards from the base 1, it being retained by the roller 4 engaging the underside of a bent-over portion of contact 3. The limit projections 39, 40 are longer in this case and engage grooves in the base. In a further embodiment (Fig. 6, not shown), the fixed contacts of the switch shown in Fig. 4 are arranged side-by-side and the roller slides towards and away from them in slots in a U-shaped bracket. The projection of the operating handle through the switch cover may be insufficient to allow gripping of the handle to control the speed of operation of the switch.

Patent GB-648757-A (GB)
Title: Improvements in winding machines for paper rolls
IPC: B65H19/22
Filed: 1947-04-03
Abstract: 648,757. Winding webs. LANGBO, G. April 3, 1947, No. 9152. Convention date, April 5, 1946. [Class 100 (i)] A machine for winding paper rolls from a web, comprises a plurality of spindles for the consecutive winding of the rolls, each of the spindles projecting from one end face of a continuously rotating drum and being associated with means for automatically cutting the paper web upon completion of the winding of a roll and expelling the completed roll along the winding spindle. The web 1 is consecutively wound on spindles 4, 5 and 6 projecting from the end face of a drum comprising end-plates 7 and 8 which are continuously rotated with a shaft 9 to bring each spindle into positions for winding, cutting and expulsion of a roll. The shaft 9 is journalled in a frame 10 while endplates 7 and 8 are rotated by a toothed rim 15 on the plate 8. The spindles 4, 5 and 6 are driven individually through friction clutches such as 13 by a common belt 14 such that only the spindle on which winding is actually being effected is driven, while the remainder act as guiding rolls. The friction clutches are operated by a cam 16 to decrease the speed of the spindles as the diameter of the rolls increases until the spindle is ultimately stopped when the roll is complete. The spindle 6, Fig. 2, carries a completed roll which has been wound during rotation of the drum from the position in which the spindle 6 occupies the position of the spindle 5. A projection 23 on a bar 20 slidable in a tube 21 engages a rotating, threaded pin 25 so that the end face 27 of a cutting device 22 on the bar 20 pushes the completed roll off the spindle. Simultaneously, a projection 23 on a bar 20 associated with the spindle 5 is disengaged from an arcuate rail (not shown) so that a cutting device 22 associated with the spindle 5 makes a quick movement to the right, Fig. 2, under the influence of a spring (not shown) to cut the web. Due to the shape of the cutting device, the remaining portion of web is carried around the spindle 5 to commence winding a fresh roll; at the same time, the spindle 5 is rotated with the clutch 13 fully engaged so that peripheral speed of the spindle is greater than the linear velocity of the paper, thus helping to retain the paper on the spindle. The free end of the completed roll may be glued to the roll by any convenient method or device. The cutting device associated with the spindle 6 is held in its extreme left-hand position by the projection 23 engaging the arcuate rail until the spindle 6 reaches the position occupied by the spindle 5 in Fig. 1, when the sequence of operations is repeated.

Title: Improvements in or relating to resistance welding apparatus
IPC: B23K11/30
Filed: 1944-05-17
Abstract: 579,527. Welding. TUCKER, N. A., and MALLORY METALLURGICAL PRODUCTS, Ltd. May 17, 1944, No. 9439. [Class 83 (iv)] A water-cooled electrode for a resistance welding machine has a tip with an axial blind hole, the bottom of which comprises an inward projection of conical shape merging at its base. into the side walls of the hole so as to constrain the water, brine or other coolant emerging from the inlet tube therein to flow outwardly in the hole in all directions radially of the axis of the inlet tube and then to flow backwardly in the hole about such tube. The tip 2 is secured in a tapered or screwed socket in a holder 1 which is provided with lateral water inlet and outlet connections 6, 11 and also with a screwed plug 5 having a reduced waist 8 and transverse holes 9 opening into a bore 10 communicating with the inlet tube 4 which is secured thereto. The bottom of the hole 12 in the tip is formed with a central, inwardly-directed, conical projection 14 so that the cooling liquid is forced thereby to assume an inverted fountain jet-like path immediately behind the operative part of the tip and to reverse its direction without losing contact with the walls at this end of the hole so as to reduce turbulence and prevent the formation of air and vapour pockets. This may be produced by drilling a flat-ended hole and then finishing by an annular cutter to produce an annular groove 13. The tube is adjustable in length to bring the discharge end into the desired position with respect to the projection. This may be effected by fitting round the screwed end of the tube a closely coiled spring 16 and adjusting by turning the spring. The lowest convolution may be bent at right angles to prevent shutting off of the coolant should the spring be unscrewed too far. Such a flexible construction can be used for cranked or bent electrode tips as shown in Fig. 3. Specification 574,862 is referred to. According to the Provisional Specification, the central projections may have inwardly curved sides.

Abstract: 1,109,832. Conveying rotary motion; positive clutches; breaking pieces. WILLIAM CROSLAND Ltd. 13 April, 1965 [6 March, 1964], No. 9487/64. Headings F2C, F2Q and F2X. [Also in Division B3]  A sheet feeding device comprises a pair of endless chains 10 which carry transporter bars 11 and which are advanced intermittently by a crank-operated mechanism comprising a pivoted lever 28, a rack-and-pinion 26, 15 and a clutch 18. The crank pin 32 is mounted in a crank disc 31 on a shaft 30 and the pin runs in a slot 29 in the lever 28. The points X and Y each 15 degrees from T.D.C. and B.D.C. respectively indicate the points at which the oscillating movement of the lever reverses. Pivotally connected to the lever is a rack 26 which reciprocates in a pivotally mounted carrier 27 and which meshes with a pinion 15. The pinion 15 is freely rotatable on a shaft 13 to which are secured sprocket wheels 12 for the chains 11. The periphery of the crank disc 31 forms a cam which reciprocates a clutch-operating push-rod 38. Secured to the pinion 15 is a disc 16, Fig. 3, which has a peripheral notch 17 and which forms one member of the clutch. The other clutch member is secured to the shaft 13 and comprises a body 20 in which a spring-loaded pin 21 is mounted between arms 19. The spring biases the head 22 of the pin into engagement with the notch 17 in the disc 16, to lock the pinion 15 to the shaft 13. The clutch is disengaged by a roller 43 acting on the head 22 of the pin 21. The roller is mounted on a slide 41 which is reciprocated by a bell-crank 39, 40 connected to the push-rod 38. Operation.-Assuming that the rack 26 is approaching the upward limit of movement, the push-rod 38 is in a lower position and the roller 43 is withdrawn from the head 22 of the pin so that the clutch is engaged. As the pin 32 reaches the position X the rack stops and the cam 31 operates the push-rod 38 to disengage the clutch and to move the end of the pin 21 into an aperture 24 in the press-frame to lock the shaft 13 and hence the chains while a press operation is performed. During this time the rack 26 moves downwards as the pin 32 moves from X to Y. At the position Y the cam 31 allows the rod 38 to move down, the clutch is engaged and the shaft 13 is rotated by the pinion 15 as the rack 26 makes a further upward movement. Safety device and stop mechanism.-The clutch part 20 is connected by two shear plates 44 to a safety roller 45 which is biased by springs 47 to move leftwards in Fig. 3. If an obstruction prevents the chains moving, the plates 44 shear and the safety roller 45 immediately pushes a sleeve 46, keyed to the shaft 13, against a link which operates a switch (50), Fig. 4 (not shown), which cuts off power to the press.
